VENTILATOR.

Application filed July 20, 1927.

proper or to hold the shutter against the ven;

tilator for closing the same.

A further obj ectis the provision of a ventilator for windows in thenature of a sub stantially rectangular frame having a reticulated facingand having doors or shutters swingable toward or at desired anglestherefrom, to permit of the desired amount of air currents passingthrough the window casing and to likewise prevent the entrance ofmoisture through the ventilator, the said ventilator being provided withadjustable slides movable through the ends thereof, to contact with andfrictionally engage the sides of a window casing.

To the attainment of the foregoing and other objects which will presentthemselves as the nature of the invention is better understood, theimprovement resides in the construction, combination and arrangement ofparts, a satisfactory embodiment of which is disclosed by theaccompanying drawings.

In the drawings:

Figure 1 is a perspective view of a ventilator in accordance with thisinvention.

Fi ure 2 is an approximately central longitu inal sectional viewtherethrough.

Figure 3 is an elevation showing the door or shutter closed against theventilator.

Figure 4 is a transverse sectional view showmg the ventilator in appliedposition.

Figure 5 is a similar sectional view illustrating the door or shutterswung to partly open position.

Figure 6 is a perspective view illustrating a slight modification.

Referring now to the drawings in detail and to Figures 4 and 5 inparticular, the numeral 1 designates a window casing, 2 the lowerslidable sash thereof and 3 the sill of the casing. Arranged on thecasing 1n contact with the sill 3 and between the beads provided for thesash 2 there is my improved ventilator. The ventilator comprises asubstantially rectangular frame 4, open at its rear and having its frontclosed by a re ticulated facing 5. The facing 5 is of the Serial No.207,232.

usual wire mesh. The upper and lower members of the frame are of metaland have flanged edges, andthe said upper and lower members areconnected at their ends by blocks 6 which may be of metal or wood. Onthe outer faces of these blocks there are fixed metal plates 7 that havetheir ends formed with ears or barrels 8 for the reception of pintles 9on the lower ends of a shutter 10. The

shutter is preferably of metal and is of a.

length corresponding to that of the frame be tween the ends 6 thereofand the upper or outer edge of the shutter 10 is bent upon itself toprovide the same with a head 11.

Fixed on the top of the frame 4 there is an angle plate 12. The innerand upstanding flange 13 of this plate is designed to contact with theinner face of the lower rail of the window sash 2 as disclosed byFigures 4 and 5 of the drawings. The outer end of this plate hashingedly secured thereto, as at 14, a strap 15. The strap is preferablyof metal and is provided throughout its length with transverselyarranged bulged or corrugated portions 16 affording inner grooves forcontacting engagement with the beaded edge 11 of the door or shutter 10and whereby the said door or shutter may be swung at desired outwardangles with respect to the frame. In addition to the corrugated portions15 the strap is formed with an offset portion 17 to engage with the headof the door or shutter when the latter is swung against the frame. Thereis a frictional engagement between the barrels 8 and the pintles 9 ofthe shutter so that the free swinging of the shutter is thus prevented.

In Figure 6 I have illustrated a slight modification in which the frameis provided with spaced reticulated portions 18 and separate shutters 19for closing such portions.

In both constructions there is arranged for slidable movement throughthe ends of the frame plates 20. Each of these plates has an offset orhooked end 21. The plates 20 are frictionally engaged by the inwardlydirected portions 22 of the top and bottom elements of the frame so thatthe free sliding of the plates is thus prevented. The offset or hool edportions 21 of the longitudinally ad iustable plates 20 are designed tobe received in the grooves in the casing 1 that prov1de the guldewaysfor the sash 2, and if desired to contact with the parting beads betweenthe casing and the sash.

The simplicity of the improvement and the advantages thereof, will, itis thought, be perfectly apparent to those skilled in the art to whichsuch invention relates when the foregoing description has been carefullyread in connection with the accompanying rawings, but obviously I do notwish to be restricted to the precise details herein set forth and,therefore, hold myself entitled to make such ceived in and frictionallyengage with the barrels, said shutter having its upper edge rounded toform the same with a bead, an angle plate fixed on the top of the frameand designed to have its upstanding flange contact with the inner faceof the bottom rail of the lower sash, a strap hingedly secured to theangle plate having an offset portion and having corrugations designedfor engagement with the head of the shutter for holding the shutteragainst the frame or at angle positions with respect to said frame,plates slid able through the ends of the frameand guided between theflanges and the top and bottom of the frame and the blocks at the endsof the frame, said plates having offset ends to he received in thegrooves for the sash m the W111- dow casing, and a reticulated facingfor the frame.

In testimony whereof I afix m y signature.
